Hi Tim, I've got a Rohde & Schwarz CMS54 radio communications tester so I will run through the alignment with that and report back.

These are important and I do them every time a version is released that had modifications to the RX. The XG-1 or XG-2 from Elecraft is cheap and excellent for doing this if you don't have a signal generator. -Tim --- Integrated Technical Services "Too much of everything is just enough." -Rob Barlow -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andy Smith Sent: Tuesday, September 12, 2006 11:29 AM To: 'Eric Wachsmann'; flexradio@flex-radio.biz Subject: Re: [Flexradio] Noise Floor Higher - SVN vs 1.6.2 Hi Eric, I don't have any database so nothing was imported, the SDR is literally just out of the box, I haven't done any calibration with either version of software, with 1.6.2 the noise floor sits at around -140dBm against -110dBm on the SVN version, on both versions I had the pre-amp set to high.

This or perhaps differing Preamp settings may account for the difference in noise floor.
